Nyob rau hauv tus Devicenet kev sib txuas lus kev sib txuas lus, peb feem ntau ntsib cov teeb meem zoo li no: qee zaum zoo thiab qee zaum tsis zoo, thiab txawm tias lub cuab yeej nquag raug txiav tawm. Ntau tus engineers ntaus nqi cov teeb meem, cable zoo, los yog node tsis ua hauj lwm, tab sis tsis quav ntsej tus yuam sij thiab qis} qhov xaus resistor. Tsis txhob ua rau tus neeg tiv thaiv me me no, nws yog tus thawj coj ntawm "uas ua kom muaj kev sib txuas lus ruaj khov ntawm tus devotetet system.
1. Vim li cas thiaj yuav tsum muaj tus devitomenet system siv terminal resistors?
Devicenet siv cov cav sib txawv ntawm cov kis las sib txawv raws li lub tsheb npav. Txhawm rau kom muaj kev ncaj ncees thiab tiv thaiv kev xav txog thiab kev cuam tshuam nrog kev cuam tshuam (cov nqi uas raug yog 121ω) yuav tsum teeb tsa ntawm ob lub tsheb npav.
Yog hais tias lub unit resistor ploj lawm, nws yuav ua rau:
- Kev Nkag Ntsej: Cov ntaub ntawv pob ntawv tau cuam tshuam rov qab rau cov kab pob tw thaum kawg ntawm lub tsheb npav, ua rau cuam tshuam rau kev cuam tshuam;
- Kev Sib Txuas Lus txawv: Node lees paub ua tsis tiav, cov teeb meem cov ntaub ntawv lossis muaj qhov yuam kev nce ntxiv;
- Qhov System tsis muaj zog: Disconnection lossis "khov" tshwm sim thaum lub network ntsaws tau siab me me;
- Nyuaj Debugging nyuaj: Cov txhaum no tshwm sim tsis xwm yeem, thiab nws yog qhov nyuaj rau nrhiav qhov teeb meem ntawm qhov teeb meem.
2. Kev teeb tsa txoj haujlwm ntawm cov chaw tiv thaiv
Raws li Odva tus Devicenet network specification, terminal restors yuav tsum tau nruab rau ntawm ob qho kawg ntawm network lub pob tw kab, uas yog:
- Ib qho resistor yog nruab rau thaum kawg ntawm lub chaw nres tsheb Master (xws li PLC maub los)
- Lwm tus resistor yog ntsia rau ntawm qhov kawg ntawm ceg uas cov khoom siv ntse tshaj plaws
3. Pom zoo lub davhlau ya nyob dav hlau tiv taus cov qauv
Hom Terminal resistor modules ntawm kev ua lag luam, xws li turck's RSM 57 {{{{3} {}, tsim qauv, thiab cov qauv IP67 tiv thaiv. Nws cov kev teeb tsa raug yog:
- Tus nqi tiv: 121ω ± 1%
- Interface hom: 7/8 "-16unf 5-tus txiv neej txuas txuas
- Txoj kev teeb tsa: Plug - hom module, yoog rau devicenet pob tw kab
- Nta: Solder - free, waterproof thiab plua plav, nrawm rau {{1} {1} {1} {}}}} Cov xaib xaib
Txawm li cas los xij, cov khoom lag luam ntawd feem ntau muaj teeb meem xws li lub sijhawm xa khoom ntev, tus nqi siab, thiab tsis txaus customization yooj yim.
Premier Cable muab Demanic Terminal resistor xaiv nrog sib npaug hluav taws xob kev ua tau zoo thiab txhawb nqa:
- Customized kab ntev thiab txuas cov hom (xws li m12 - coded lossis 7/8 ")
- Ib -} daim waterproof txhaj tshuaj
- Muaj Qib IP67 Kev Tiv Thaiv
- Loj - heev ntim ceev tus xa thiab me me- batch customized ntau lawm
4. Cov teeb meem installors thiab daws cov lus pom zoo
| Yuam Kev Ua Yuam Kev | Kev piav txog | Tsos mob | Kev daws teeb meem pom zoo |
|---|---|---|---|
| Tsuas muaj ib qho kev txiav tawm tiv thaiv | Tsuas yog ib tug 120ω resistor siv hloov ob | Kev sib txuas lus tsis ruaj khov, cov ntaub ntawv sib npaug poob | Nco ntsoov tias 120ω resistor yog ntsia rau ntawm ob tus tswv (plc) thiab qhov deb tshaj plaws i / O module |
| Kev txiav tawm tiv thaiv tau muab tso rau hauv nruab nrab ntawm lub tsheb npav | Resistort tsis nyob ntawm lub network xaus | Tej yam tsis teb los yog qhia cov lus sib txuas lus | Txav tawm tsam cov haujlwm kom raug: ib qho ntawm txhua qhov kawg ntawm cov kab pob tw |
| Ntau tshaj ob qho kev txiav tawm tiv taus | Tshaj -}} term term្ termດ TESTHER TAS NRHO NETWORK Impedance | Cov tsheb npav tsis tuaj yeem pib, kev nyeem tsis meej ntawm kev nyeem | Tshem tawm cov neeg tiv taus ntau tshaj, tawm tsuas yog ob - ib ntawm txhua lub network xaus |
| Tsis kam tiv taus tus nqi (tsis yog 1200) | Siv 100ω, 150ω, lossis lwm yam tseem ceeb | Kev piav qhia kev nkag mus, kev tsav tsheb tsis muaj tsheb | Hloov nrog kom raug 120 txwv tsim nyog tsim rau devicenet siv |
| Xoob lossis tsis zoo nyob rau hauv txuas | Tsis raug zawm lossis hnav - tawm cov txuas | Sib tw cim kos npe, voltage poob, ntaus ntawv | Siv high - Cov khoom siv sib txuas zoo (piv txwv li Premier Cable M12 lossis 7/8 "Devicenter Cles); Khij txhua lub sijhawm |
| Tsis muaj kev txiav tawm tsam | System tsis muaj kev cuam tshuam kev sib txuam | Network tsis ua haujlwm | Nruab ib qho 120 feeb resistor ntawm txhua qhov kawg ntawm Devicenet lub cev kab |
| Yuam kev txhim kho ntawm cov kab poob qis (tsis yog pob tw) | Qhov chaw tsis raug ntawm cov kab laum lossis cov khoom seem | Teeb liab tsis muaj zog, cov kev sib txuas lus tsis zoo | Yuav tsum tau muab ntsia rau ntawm ob qho kawg ntawm pob tw cable |
5. Cov ntsiab lus: Cov khoom siv me me, lub luag haujlwm tseem ceeb
Hauv Devicenet system, lub cable yog lub cev pob txha, thiab lub davhlau ya nyob twg yog qhov "lub siab nruab nrab" uas tswj qhov sib npaug ntawm kev sib txuas lus. Tsis txhob cia tus neeg tiv thaiv me me uas tsis quav ntsej luag qhov kev ruaj ntseg ntawm tag nrho cov kev ua haujlwm.
Premier Cable muab cov Cabs tshwj xeeb (M12 thiab 7/8 "Kev sib txuas lus zoo li cov khoom siv sib txuas, ntxiv rau cov khoom siv tshwj xeeb, ntxiv rau corrosion thiab corrosion tsis kam.
